would anyone happen to have the spec for the acceptable compression for a 1962 (Biscayne) 235 , my gut feeling is that it's a bit on the low side:
1- 80psi
2- 70psi
3- 65psi
4- 70psi
5- 75psi
6- 75psi
tha engine has been sitting since '85 and only started a few tiimes since , I ran it for about 15 minutes last May. I conducted the compression test dry (ie. without squirting oil into the cylinders)
thanks again
